Flow of matter in the immediate vicinity of a T Tauri type star with a constant dipole magnetic eld on a two-dimensionalaxisymmetric computational grid is simulated. Within the framework of a nonstationary MHD approach, the interaction ofa jet, a partially ionized gas of the stellar corona, and a protoplanetary disk is considered. The model takes into accountthe degree of gas ionization, optically thin cooling, anisotropic thermal conductivity and viscosity. Numerical modeling isperformed using the free PLUTO package.
